Lajos Vajda (Hungarian: Vajda Lajos; 1908, Zalaegerszeg – 1941, Budakeszi) was a Hungarian painter.
He was a student of István Csók at the Hungarian Academy of Fine Arts in 1927-30.
His last abstract surreal drawings foreshadow the horrors of World War II.
He died of tuberculosis in 1941.
He is considered to be the most distinctive of the Hungarian avant-garde movement.
His art influenced generations of Hungarian artists among them the members of the European School Art Group (established in 1945) and the Vajda Lajos Studio (established in 1972).
His works can be found in museums and private collections, among them in the Hungarian National Gallery in Budapest and in the Vajda Lajos Museum in Szentendre, Hungary.
